Figure 5. Transmission electron microscope image of a section of the Acrodisk filter. The filter is dark region at the bottom of the image. Particles on the filter are identified by major chemical elements. One cell (identified by internal structures) is located on the filter. The gray matter on top of the filter "matte" may be polysaccharide.
